I thought the point of the USB card writer module that comes with the PE-Design is specifically to transport your design, whether editted or not, to your machine.  I just got the Brother 770 which reads designs from your USB flash drive.  I purchased the PE-Design Ver.7 from a friend basically for its software but when trying to open Layout & Editing, it says that the USB module is not attached.  I just wanted to create a design and save it to my flash drive--not to the embroidery card through the module.  Did I install the software correctly or do I really need to have that module attached to my computer even if I'm saving my design to my flash drive?

Thank you all for your help!

You can not use PEDesign in any format with the use of the card reader writer.  This piece of hardware is necessary for opening designs and transporting them to a card.  If you have a pes embroidery file you can send it to a USB and open in the machine....providing that file was created for the recognized hoop sizes in your machine.  You can not open and view pes files in your computer without the hardware attached, even if you have the software installed. 

You can also consider purchasing Brother's BES lettering program.  This is a multi-faceted program that will allow you to not only open and view your design with out the "box" , you can also add letters, change the size of the image or add other designs to your design.  For more information on this program click on the blue letters.  Don't forget that you can get lots of new designs for your machine at http://www.ibroidery.com ---lots of new designs from Disney, Warner Bros. and Nickelodeon too! 

Thank you for your response Pat.

That's what I wanted to do...just use the software since I dont need to save it to the embroidery card, I can save it to the usb stick.  So PE-6 lets you do that?  I'll look into it.  Thank you so much Pattiann!
